    Electronic switching- memory- and sensor devices from a discontinuous graphene and/or graphite carbon layer on dielectric materials
    (2013-05-14) Tour, James M.; Li, Yubao; Sinitskiy, Alexander; Rice University; United States Patent and Trademark Office
    Electronic devices comprising a dielectric material, at least one carbon sheet, and two electrode terminals are described herein. The devices exhibit non-linear current-versus-voltage response over a voltage sweep range in various embodiments. Uses of the electronic devices as two-terminal memory devices, logic units, and sensors are disclosed. Processes for making the electronic devices are disclosed. Methods for using the electronic devices in analytical methods are disclosed.

    Vertically-stacked electronic devices having conductive carbon films
    (2013-03-12) Tour, James M.; Li, Yubao; Sinitskiy, Alexander; Zhong, Lin; Dong, Mian; Yao, Jun; Rice University; United States Patent and Trademark Office
    Vertically-stacked electronic devices having conductive carbon films are disclosed. The vertically-stacked devices exhibit non-linear current-versus-voltage response over a voltage sweep range in various embodiments. The vertically-stacked devices may be assembled into arrays where the vertically-stacked devices may be electrically addressed independently of one another. Uses of the vertically-stacked electronic devices and arrays as two-terminal memory devices, logic units, and sensors are disclosed. Crossbar arrays of vertically-stacked electronic devices having conductive carbon films and nanowire electrodes are disclosed.
